East 20th Street closed: water main replacement keeps road shut until April

Crews are starting a water-main rehabilitation this week on East 20th Street in Cheyenne, a project that will close the street and could disrupt parking, driveway access and water service for nearby residents and businesses. The City of Cheyenne Board of Public Utilities says the work is expected to wrap up by mid-April, though weather or supply delays could stretch the schedule.

The contract for the work has been awarded to Aztec Construction Co. and is part of a broader BOPU effort to replace aging pipelines across the city. Officials say the intent is to improve long-term reliability, but the short-term impact will include a full closure of East 20th Street between Logan Avenue and East 21st Street.

What to expect during construction

Drivers should plan detours; the closure removes through traffic on a block that normally serves local commuters and deliveries. Parking will not be allowed in the work zone during active hours, and crews may occasionally work on Saturdays.

BOPU warns that access to some driveways will be interrupted briefly at times. When that happens, residents are expected to park outside the active work area until access is restored.

• Location: East 20th Street, between Logan Avenue and East 21st Street
• Work hours: 7 a.m. to 6 p.m., Monday–Friday (occasional Saturdays)
• Road status: Full closure of the block during construction
• Expected finish: Mid-April (subject to weather and materials)
• Contractor: Aztec Construction Co.
• Possible impacts: Temporary driveway restrictions, no parking in the right-of-way, and planned or emergency water shutoffs

Planned water shutoffs will be coordinated by the BOPU, but officials caution that unplanned emergency outages remain possible while crews are working on the main. Households that rely on city water should prepare for short interruptions and consider keeping a small supply of water on hand during the construction window.

How residents and businesses can prepare

Signage and traffic control will be installed around the site; nonetheless, expect delays and altered delivery or service schedules. Businesses on or near the work zone may want to notify customers in advance and reschedule inbound deliveries during core construction hours.

For short-term driveway blockages, the city asks affected residents to relocate vehicles ahead of work hours and use nearby streets for parking. Monitor official BOPU communications for scheduled shutoff notices and updates on the timeline.

While the work aims to reduce future breaks and interruptions by replacing deteriorating pipes, the immediate consequence will be inconvenience for people who live, work or travel through the area. Keeping informed of updates from the Board of Public Utilities will help households and businesses minimize disruption.
